Grail(TM) is a web browser written in Python

I was taking a look to see if I could help and it became clear there are several transformations that need to be applied across the whole code base before being able to work on individual files.

The first thing I notice compared to Python 3 is the "string" module which appears to refer to a module that was available in Python 1 and 2 but not in 3: https://docs.python.org/release/1.4/lib/node49.html

Doing a naive search through the code bade I found the following methods exceptions being used and I've listed their replacements:

string.capitalize -> str.capitalize 
string.capwords -> str.title
string.splitfields -> str.split
string.upper -> str.upper
string.lstrip -> str.lstrip
string.replace -> str.replace
string.joinfields -> str.join
string.atol -> int
string.rfind -> str.rfind
string.lower -> str.lower
string.whitespace -> string.whitespace
string.split -> str.split
string.atoi -> int
string.digits -> string.digits
string.maketrans -> str.maketrans
string.rstrip -> str.rstrip
string.index -> str.index
string.atof -> float
string.strip -> str.strip
string.translate -> str.translate
string.find -> str.find
string.join -> str.join

I also found the following exceptions which all look like they can be replaced with ValueError:

string.atof_error
string.atoi_error
string.atol_error

I am preparing a PR with the following steps:

1. Find any case where a name is bound to the built-in str, and change the name to str_
2. Replace the above methods
3. Replace the above exceptions

I plan to automate the bulk of the replacements and I don't have any test cases to prove it's the correct approach as the code base itself does not run. So let me know if there's any preferred other way you think this should be approached.

I am changing the files according to Python 3 and this At appears many times ? What is this At ? Is it a class(I'm guessing because of naming convention rule) or is it function(less chance I think) ? And what is the alternative for this in Python 3 ?

Do you want to run this using Python 2 or 3?

If it is to have a future it should probably use Python 3, but given that it was written for Python 1, it would be simpler to start out with Python 2.

If you stick to Python 2 you won’t have to deal with converting print statement to calls and other 2to3 stuff. Plus if you find it is hopeless you will have wasted less time... :-)

I saw that you're changing all regex occurences to re, which is a good idea. But you've overcomplicated the import by writing

import re as re

This can just be

import re

There is no module like rfc822 in python 3. It was removed in python 3. So now I want to ask which alternative shall we use because I don't have much experience with these two modules. There is email module and plone.rfc822 module. I think plone.rfc822 will be similar to rfc822 so we don't need to change much. What is your opinion ?

I have searched on internet and as far as my knowledge there is no exception like UndefinedStyle. Can you tell @gvanrossum what kind of error did you want it to handle ? Maybe the name for that exception is changed.

I was thinking about whether we should keep going with tkinter or change the module. After researching about it on internet I have come to the conclusion that PyQt5 module is better than tkinter. This module provides a tool QtDesigner which will help us in building the GUI for our app. Of course if we start with a new module we'll have to start everything from scratch. All the tkinter code will be useless. I want your opinion on it sir. Should we go with tkinter or try some other module like PyQt5.

def more_complete_challenge_parse(self):        
        return

        challenge = headers['www-authenticate']
        # <authscheme> realm="<value>" [, <param>="<value>"] ...
        parts = string.splitfields(challenge, ',')
        p = parts[0]
        i = string.find(p, '=')
        if i < 0: return
        key, value = p[:i], p[i+1:]
        keyparts = string.split(string.lower(key))
        if not(len(keyparts) == 2 and keyparts[1] == 'realm'): return
        authscheme = keyparts[0]
        value = string.strip(value)
        if len(value) >= 2 and value[0] == value[-1] and value[0] in '\'"':
            value = value[1:-1]

In this code why did we do all this if we just wanted to return nothing. The code below return won't get executed so why did we write all this code. What is the purpose of it @gvanrossum ?

I haven't checked each and every folder so I don't know the total number but some files seem to be missing like grail.py Why did you delete those @vadmium ?

Hi Everyone.,My name is Niyant. I am here to help you for updating of browser.... I hope I can give my best... I am person of brain storming ideas and I have experience of begginer in python... So I hope you don't mind it and helping each other here will be key feature of here... And believe me I can give you so woowwwww!!!!! Ideas that you have never thought or ever imagined.... I am ending with this for a new start of new Journey.... And I am thankful to GVR sir and originator PPP..... Thank you for understanding me and feeling I am useful too you

Problem: While running python3 grail.py an error occurs ImportError: cannot import name 'tktools' from 'utils' (unknown location)

Notes: tkinter was installed using sudo apt install python3-tk utils installed using pip3 install python3-utils

Specs: Python 3.9.5 PIP 20.3.4 Ubuntu 21.04 Kernel 5.11.0-31-generic

In the Reader.py file(also in some other files) there was one place where instead of regex.compile I wrote re.compile now the problem is that regex.compile took translate parameter which was an optional parameter. This parameter translated the string and the pattern before comparing the string with the pattern. I have come up with one solution. I'll convert the pattern and the string into casefolded strings beforehand and then use the compile function and this time I'll not have to mention that translate parameter. Meanwhile if anyone knows any alternate function for regex.compile which works in Python 3 then please inform me and I'll use that.

Hi Everyone Good Evening PPP

I got one more idea if we can use public search history which they are searching and we can put that also if public doesn't like or want to change quote panel with their search and Trending searches.....

I hope you will like my idea....

Hi Everyone Good Evening PPP Originator.... I came up with idea that we can put motivational quotes while in free time they can have motivation...and we will update these quotes every time whenever he/she opens it.... So I hope u liked my idea...

1. We are targeting the latest Python which is Python 3.9
2. This project is trying port Grail from Python 1 to Python 3.9
3. After the implementation is done we want to improve this browser to add more functions and make it user-friendly
4. In future, we might also make an incognito like tab inside this browser

Current Status Currently we are trying to make an implementation of the existing code into Python 3.9

If you have any question which I wasn't able to answer feel free to ask that question inside this issue.
